A dog whistle is designed to produce a sound with a frequency beyond that which can be heard by humans. If a particular whistle produces a sound with a frequency of 2.5x10 4 Hz, what is the sound’s wavelength? Assume the speed of sound in air is 343 m/s.

A drum is struck, producing a wave with a wavelength of 1.10 meters and a speed of 343 m/s. What is the frequency of the wave? 3. Sonar is a device that uses reflected sound waves to measure underwater depths. If a sonar signal has a frequency of 288 Hz and the speed of sound in water is 1,498 m/s, what is the wavelength of the sonar signal? 4. A dog whistle is designed to produce a sound with a frequency beyond that which can be heard by humans. If a particular whistle produces a sound with a frequency of 2.5x10 4Hz, what is the sound’s wavelength? Assume the speed of sound in air is 343 m/s. Electromagnetic Waves: 5. [Radio waves] A certain FM radio station broadcasts electromagnetic waves at a frequency of 9.05x10 7Hz. These radio waves travel at a speed of 3x10 8m/s. What is the wavelength of these radio waves? 6. [Visible light] A student asks your physics teacher what his favorite color is. Your teacher provides the following straightforward and understandable response: “The wavelength of light that corresponds with my favorite color is 623 nanometers”. Use the speed of light to calculate the frequency that corresponds to this wavelength. 7. Using values from this assignment: How does the speed of sound in air compare to the speed of sound in water? 8. Using values from this assignment: How do the speed of sound and light compare? 1.31 meters .+

Samira is riding on a bus moving at 14 m/s when she hears a whistle on the road ahead of her. If the bus is moving towards the whistle and the whistle emits a 2400 Hz sound, what frequency sound does Samira hear? You can assume that the whistle is not moving and that the speed of sound in air is 350 m/s.2496 Hz2400 Hz 2154 Hz2304 Hz

Frequency of a wave travelling from source to receiver is 200 Hz. If the speed of sound wave is 100 m/s.Wavelength of wave is;

Find the wavelength of sound for frequencies up to 120 kHz at which a bat can hear it. Take the speed of sound in air as 344 m/s.2.8×10−32.8×10 −3 m 2.4×10−22.4×10 −2 m2.8×10−22.8×10 −2 m 2.4×10−32.4×10 −3 m

A sound wave travels at a speed of 340 m/s. If its wavelength is 1.5 m. What is the frequency of the wave?
